* Turtles are cold-blooded. One way they regulate their temperature is by basking.

* Some turtles, such as the Musk turtle, emit an odor when startled.

* Not all turtles and tortoises hibernate.

* The blood of hibernating turtles acts somewhat like antifreeze, allowing it to tolerate cold temperatures.

* Some female turtles produce eggs four years after mating.

* Many species make sound, especially while mating.

* Incubation temperature determines the sex of the hatchling.

* All turtles lay their eggs on land.

* Hatching turtles have an egg tooth at the end of their beak to help open the egg.

* Some land turtles can out run a human.

* The smallest turtle, the Speckled Padloper is 4". The largest is the Leatherback sea turtle, that can reach up to 10' in length.

* Turtle shells DO break.

* The color and patterns of each species allows them to blend into their natural environment.

* Turtles can regrow bony and keratin tissue.

* Not all turtles have hard shells. For example, Softshell turtles and sea turtles have flexible shells.

* Box turtles are not the only turtles with a hinge to allow part of their shell to move.

* Turtle shells are built into their skeleton.

* The top shell, the carapace, is made up of approximately 50 bones.

* Counting the growth rings on the scutes (scales) of the top shell does not tell the age of the turtle or tortoise.

* Some turtles have hinges on their shells to enable them to close up tightly inside.

* Turtles cannot protrude their tongues from their mouths.

* Aquatic turtles have streamlined shells to help them move through the water. They also have webbing between their toes.

* Aquatic turtles must be in water to eat.

* Tortoises only go to water to drink. They do not swim.

* Some tortoises can dig burrows 45 feet long.

* Many turtles are expert climbers.

* Land turtles ears are sensitive to ground vibration.

* A group of turtles is classically called a bale.

* One of the most common health problems is MBD, Metabolic Bone Disease, caused by improper diet and care.

* All turtles and tortoises do not have the same habitat and nutritional requirements. Therefore, it is very important to research the kind of animal you have or plan to own.

* Turtles have good eyesight, seeing in full color and a strong sense of smell. They have excellent hearing and sense of touch. Their shells have feeling due to nerve endings.

* Instead of teeth, turtles have a sharp beak for eating. Depending on species, the beak may be scissor-like, hook-like, or serrated. The earliest turtles did have teeth and could not retract their head.

* Some turtles can live up to a year without food.

* Tortoises from dry environments have thick scales on the skin to prevent fluid evaporation. Aquatic and semi-aquatic turtles have thinner skin and lack heavy scales.

* Turtles shed their skin in small flakes rather than pieces like other reptiles.

* Sea turtles can swim up to 35 mile per hour.

* Several species, including the American Box turtle, can live to be over 100 years old.

* One documented case of longevity is of an adult Indian Ocean Giant Tortoise. After being captured and estimated to be 50 years old, it lived another 152 years in captivity.
